SDK fails to load in Godot distribution on Steam due to `scout` runtime incompatibility

[GaelFG-Anderon]

How do you use Sentry?

Sentry Saas

Sentry SDK version

1.5.0

How did you install the SDK?

AssetLib

Godot version

v4.6.1.stable.official (via Steam distribution)

Which platform?

Linux

How to reproduce

(probably broader scope, I just give my case :) )

• On Fedora 43, install Steam (https://docs.fedoraproject.org/en-US/gaming/proton/)
• On Steam get Godot (currently 4.6.1)
• Launch Godot and add Sentry
• launch empty scene

Expected result

• The library load

Actual result

(note : 'gael' is just my username on this computer)
The libcurl.so.4 provided by steamlinuxruntime ( version 4.2.0) is rejected

--- Debug adapter server started on port 6006 ---

The problem can be manually resolved by modifying the symbolic link /home/gael/.local/share/Steam/steamapps/common/SteamLinuxRuntime/var/steam-runtime/pinned_libs_64/libcurl.so.4 to point toward
the curl version bundled with fedora (4.8.0) but it's annoying, and Steam seems to rollback the change after some time (updates I assume, it break sometime and the link is reverted).

I'm really not familiar neither with linux binary library or libcurl so I don't know what would be better :

• make the libsentry.linux.debug.x86_64.so compatible with the steam pinned version of curl
• bundle a more recent curl version
• link to the distribution packaged version and not the steam linux runtime one
• some other solution :)

Additional supposition :

I found lot of mention of error with "version `CURL_OPENSSL_4' not found" : it seems the version flag is only available with a specific compilation flag, and so some custom compiled version (like the steam linux runtime one) don't provide it.

I can provide the steam libcurl stock bundled version if requested.

Hi @GaelFG-Anderon! Have you tried sniper runtime? If I remember correctly, this problem is with the oldest Steam runtime - with scout.

[GaelFG-Anderon]

Hello, no i will check thanks :)

[limbonaut]

sniper runtime is recommended by Valve for all new Linux native games. See:
https://gitlab.steamos.cloud/steamrt/steam-runtime-tools/-/blob/main/docs/slr-for-game-developers.md#native-linux-games-targeting-steam-runtime-3-sniper

Previously reported here: #125. Should probably add this to the docs 🙂

[GaelFG-Anderon]

After a bit of reading and testing :

• Yes the 'problem' seems to be that by default the steam version of godot is targeting the scout runtime (by default setting from steam sdk documentation) .

• As a user of the Steam Godot version, I cannot 'force' the Godot editor to launch on a more modern steam linux runtime (only proton version and scoot appear on the menu :

• The solution according to the documentation is to run the (I think really badly named :p) compatibilty mode Legacy Runtime 1.0 which use the linux distribution librairies :

edit : doc link : https://gitlab.steamos.cloud/steamrt/steam-runtime-tools/-/blob/main/docs/slr-for-game-developers.md#sniper

But when launching the godot editor, it then do load another link to libcurl.so.4 but it is still not my native distrition one but another pinned version which is also 4.2:

There is probably a way to get it to use the correct version but I will probably 'just' use the non steam distributed Godot version, which work with Sentry :)

Thanks for you help (and the Godot wrapper and Sentry since you seems to work for them, it's VERY cool and usefull ! ) and sorry for the issue more "Steam linux runtimes are complicated" than Sentry plugin bug :)

[limbonaut]

Thanks for clarifying! I was aware of the scout runtime compatibility issue, but didn't realize that Godot distribution on Steam has it too. Maybe we can figure out something in a future release. Some really good details - thank you!

[limbonaut]

I think, we should keep it open as it's a valid concern that the SDK doesn't work in Godot editor from Steam.
